How can PHP developers efficiently handle large files when calculating CRC sums?

When dealing with large files in PHP and calculating CRC sums, developers can efficiently handle the process by reading the file in chunks rather than loading the entire file into memory at once. This approach helps in reducing memory usage and processing time when working with large files. 

$file = "large_file.txt";
$crc = hash_file("crc32b", $file);
echo $crc;
